The TPS79501DCQ can handle input voltages up to 6.5V, but it's recommended to keep the input voltage below 5.5V for optimal performance and to prevent damage to the device.
To ensure the stability of the output voltage, it's essential to use a suitable output capacitor with a value between 1uF to 10uF, and an ESR (Equivalent Series Resistance) of less than 1 ohm. Additionally, the input capacitor should be placed as close to the VIN pin as possible.
The minimum input voltage required for the TPS79501DCQ to operate is 2.2V. However, the device can operate down to 1.7V with reduced performance and output voltage regulation.
The TPS79501DCQ is rated for operation up to 125°C, but the device's performance and reliability may degrade at high temperatures. It's recommended to derate the output current and voltage according to the temperature derating curve in the datasheet.
The output voltage of the TPS79501DCQ can be calculated using the following formula: VOUT = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin. The output voltage range is from 0.8V to 5.5V.
